Answer:
The ground is shaken 10 times less by a magnitude-4 quake than by a magnitude-5 quake.
Explanation:
The Richter scale is a system developed by American scientist Charles F. Ritcher to measure the magnitude of earthquakes according to the extent of waves detected by seismographs. In that respect, the larger the earthquake in the scale of Richter, the more damage it causes. Thus, a magnitude-5 earthquake makes the ground shake more and produces more considerable destruction than a magnitude-4 quake.
